Studies on in vitro antioxidant activities of nine diff erent fruit tree leaves collected from Mediterranean region of Turkey

To investigate antioxidant of the methanolic and water extracts obtained from nine different fruit tree leaves(avocado, walnut, mulberry, fig, carob, lemon, pomegranate, grape, and loquat) collected from Mediterraneanregion of Turkey. The antioxidant activities were evaluated with different in vitro antioxidant assays includingphosphomolybdate assay, free radical scavenging assays (•OH, NO, and O2−), β-carotene/linoleic acid testsystem, and ferric reducing power. The contents of saponin and tannin in extracts were also determined. Thepresent study suggests that the extracts were good radical scavengers. These results suggest that the extractsexamined should be beneficial as a source of natural agents for the food industry and pharmacological applications
